Xcode [8] Editor scrolls on its own?

Question

Environment

• Xcode 8
• MacOS 10.11.6
• MacBook Air (circa 2013)

Problem

I've noticed recently that the Editor in Xcode seems to periodically scroll-up on its own. Which I, at least, find very annoying.
I've looked at a couple of other postings:
• Xcode scrolls text while typing
• XCode auto-scroll when pressing Command after a text selection
But neither of them seem to provide a solution for me, as I'm not pressing the Command key and I'm not using multiple fingers on the touch-pad.
It seems to happen most frequently when I'm working on code near the bottom of the file, I haven't been able to narrow down the cause-and-effect scenario more than that just yet.

Query

• Has anyone else noticed this?
• Has anyone figured out a way to stop it?
• Is there a reasonable way to report this to Apple? There doesn't seem to be an Xcode section on the http://www.apple.com/feedback/ site.

Try to disable your XCode theme if you have one. We ended up with that bug by doing this trick!
